Presentation

minimal degree	μ(G) = 18
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 18 points:

(1,2)(3,4)(7,8)(15,16,18,17);(11,12,13,14)(15,16,18,17);(3,5,4,6)(9,10);(7,9)(8,10)(15,17,18,16);(5,6)(7,9,8,10)(11,12)(13,14);(3,5)(4,6)(7,9)(8,10)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((1,2)(3,4)(7,8)(15,16,18,17), (11,12,13,14)(15,16,18,17), (3,5,4,6)(9,10), (7,9)(8,10)(15,17,18,16), (5,6)(7,9,8,10)(11,12)(13,14), (3,5)(4,6)(7,9)(8,10));
